Its a giant shock absorber for bridges. It is usually attached in the area of the substructure, between the sofit and the abutment wall. Its primary job is to minimizes movement during seismic activity. I am a bridge maintenance supervisor in California and I have only seen them on longer bridge spans.

Most individuals will employ a professional to install chimney dampers. However there are tutorials on many chimney maintenance topics including the installation of dampers on Chimneycricket.

One can find more information about steering dampers by vising a local Department of Motor Vehicles and scanning/reading through the available brochures. Most Department of Motor Vehicles have free brochures and pamphlets regarding steering dampers.
Some rooms need more airflow than others, and sometimes there is a temperature disparity between rooms and/or levels in your home. regulate the airflow rate in the duct can help to alleviate these issues. This can be done by regulating what is called dampers in the system. There are basically three types of dampers - Face, Branch, and Main dampers. Face dampers are the ones that are on the face of the register itself.
